Hi,
An enemy that is being detained does not (have/has) any rights. The writer of this sentence needs to have a look at the Geneva Conventions.
Have = plural
has = singular The inflection is in the auxiliary 'does'. Use 'have ' as the base verb..
Does the -have- refer to the rights or the enemy as the subject? The subject is 'an enemy'.
Also my second question, what is the difference in
1. An enemy that is detained When they catch him, 'he is detained (by his captors)'. After that, he is in a state of 'being detained'.
2. An enemy that is being detained
Best wishes, Clive
